4. Conclusion
The present investigation has shown that guava fruit treated
with pre-harvest sprays of EFF (0.015% hexanal) at 4 and 2 weeks
before harvest and packed in CFB boxes (with 5% ventilation) most
efficiently retained the fruit quality attributes up to 28 d during
cold storage at 6–8 C and 90–95% RH. The present study on guava,
further confirms the results from previous, and currently
undergoing studies on temperate and tropical fruit regarding
the utility of hexanal formulations for extending the shelf life and
maintaining or improving the quality characteristics in harvested
fruit.
